Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey Jan 2011

Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey

Bulletins 4000 -

For plants to grow in agricultural soils, roots and emerging shoots must be able to force their way through the soil. In soils of high strength, this growth is physically restricted. High strength soils may be due to natural soil characteristics and conditions or develop as a result of agricultural practices and may be in layers or throughout the soil profile.

In agriculture, high strength soils commonly occur as a result of compaction. Compaction of agricultural soils can be in the surface (often caused by stock trampling or rain drop splatter) or in the subsurface (usually in a layer at …


Avoiding The “Fat” Of The Land: Case Studies Of Agricultural Nutrient Balance, David Weaver, Simon Neville Jan 2003

Avoiding The “Fat” Of The Land: Case Studies Of Agricultural Nutrient Balance, David Weaver, Simon Neville

Journal articles

Let’s start with a simple analogy: if a person eats more than they need, they gain weight. That is: if our feed inputs (kilojoules in) are greater than our outputs (exercise — kilojoules out) then we will gain weight (kilojoules in storage).That’s our fat. If, on the other hand, our feed inputs are less than our outputs, then we will lose weight.And if our inputs are the same as our outputs, our weight will remain constant. In general, the further away you are from an ‘ideal’weight, the greater the health risks. And yes, other aspects of your body management — …

Visions For Agriculture, Department Of Agriculture, Western Australia Oct 1992

Visions For Agriculture, Department Of Agriculture, Western Australia

Agriculture reports

This workshop grew out of a conversation between Maurice Barnes, a Trayning farmer and member of the Research Advisory Committee of the Dryland Research Institute, and Steve Porritt, the officer in charge of the Dryland Research Institute at Merredin. Maurice was interested in the idea of posing the question 'What would agriculture be like if we had known as much about this landscape in 1829 as we know now?', to a group of farmers and others interested in the central wheatbelt and its future. Maurice saw this question as a first step toward achieving some shared vision for the future …


Agricultural Progress On The Ord, D A. Mcghie Jan 1986

Agricultural Progress On The Ord, D A. Mcghie

Journal of the Department of Agriculture, Western Australia, Series 4

This is the first of occasional articles describing the experimental and commercial activity on the Ord River Irrigation Area (ORIA) in Western Australia's Kimberley region.

Against a background of extensive recources of land and water, a sometimes cimatic advantage and a complementary disadvantage of a remote location, agriculture on the Ord has swung from various monocultures to a broadly based and diversified production. In 1986, the value of agricultural production on the Ord will approach values equivalent to those of the cotton era for the first time since the demise of that industry 12 years ago.

Kimberley Research Station Progress Report, 1964 : Introduction, W M. Nunn

Journal of the Department of Agriculture, Western Australia, Series 4

THE Ord Irrigation settlement has recently planted its second commercial crop of cotton.

Research and planning toward the development project has been systematic over the last 20 years and has included hydrological surveys and dam-site investigations by the Public Works Department soil and topographical surveys by both the Department of Agriculture and C.S.I.R.O., and concerning farming methods both by research station investigations and by pilot farming.
